JONAH H. CAMPBELL, OF HOLLIS, OKLAHOMA.

FRONT-WHEEL BRAKE FOR VEHICLES.

Application filed December 12, 1911.

To c?! Ili/tom 'it may concern.

Be it known that I, JONAH H. Cinnamon, a citizen of the United States, residing at Hollis, in the county oft Harmon and State of Oklahoma, have invent-ed certain new and useful vimprovements in Front-l heel Brakes for Vehicles; and l do hereby declare the following` to be a full, clear, and exact description oit the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to brakes and more particularly to 'tront wheel brakes for vehicles.

An object ot the invention Yis to provide a brake which may be readily applied to the front Wheels otl a wagon or other vehicle t'rom a position rearwardly ot said wheels.

Another object is to provide a brake o't` this character which may be controlled from the drive1"s seat.

A further object is to generally improve the construction and op-eration of th-e t'ront wheel brake.

@ther objects and advantages will be hereinafter set it'orth and pointed out in the specification and claim.

ln the accompanying drawings whichA are made a part otl this application, Figure 1, is a side View ol a wagon with my improved brake applied thereto, two ot' the wheels being removed to more clearly show parts ot the brake. Fig. 2, is an enlarged detail View of one of the brake beam holding yokes. Fig. 3, is a plan View of one oit the connecting rods. Fig. 4t, is a side view of the same. Fig. 5, is a plan View oit the front running gear and brake mechanism, and, Fig. 6, is a :Front view of the same.

Referring more particularly to the drawings in which similar reference numerals designate corresponding parts throughout the several Views, 1 represents the Wagon body, and 2 and 3 the rear and vfront axles, carrying the rear Wheels 4t and the front Wheels 5, respectively.

The rear and front axles 2 and 3, respectively, may be connected by the usual reach pole G, upon th-e upper face of which is carried the movement limiting block 7 adapted -tor engagementagainst the under side of the bottom of the Wagon body 1, as will be later more fully described.

Secured upon the front axle 3 are the hounds 8 between the Ytorward ends of Which is secured the tongue 9. The rear Specification of Letters Patent.

ends oil the hounds 8 are connected by the connecting bar 10 which serves to brace said hounds at their rear ends. The hounds S also have secured to their rear ends the parallel cnds oil the beam holding yoltes l1, by means ot' suitable bolts l2 or other securing means. '.lbe yolecs Ill project rearwardly ot the rear ends oit the hounds S and positioned through said yohes is the brake bca 1n 13 which projects to either side ot' the yokcs 1l to a distance slightly beyond the periphery olli the 'trout wheels 5.

The trout end ol the reach pole is preterably pivoted. by means ot' the hing bolt 1-.l, between the t'ront axle and the bolster 15 and works over the connecting bar 1() and brake beam 1?. 'lhe brake beam l?) carries thc brake shoes 'lo near its opposite ends lor engagement with the periphery olf the t'ront wheels 5 at a pointy slightly above the plane ot' the axle 23 and hubs ol the wheels At suitable points between thc brake shoes 16 and the yokes '11. the threaded ends of the connecting rods vI7 are passed horizon-- tally through the brake beam 13 and the nuts 18 screwed up against the opposite sides ot said beam to hold the rods 17 against independent movement. The forward ends ot the rods 17 are 'torlted and perforated, as showa at 1f), 'lor engagement upon opposite sides ot the similarly perforated olt-sets or arms 2O ot the rock shaft 21, said 'forked ends being loclted with the arms f2() by rivets or other suitable fastening means passed through the `pei-'Forations oit said 'forked ends and arms.

The rock shalt ill is positioned 'forwardly otl the front axle 3 and slightly below the hounds S and may be secured to said axle in any preterreil manner such as by means otf the clamps i2?, which have their central portions engaged around the lhatt and their opposite ends drawn together by mains of the bolts Q23, said clamps being bent between their ends and their central portions, 'tor engagement around the axle 3, as clearly shown in Fig. 1. One arm E20 ol the rock shatt 21 is continued upwardly to form the brake controlling` lever 211- adapted for en gagement between the wagon body 1 and the front wheel 5, the upper end of the lever assuming a position adjacmit the drivers seat 25.

Then it is desired to apply the brake shoes 16 to the wheels 5, the lever 24 is thrown forwardly, winging the rock shaft 21 within the clamps 22 and drawing the connecting rod 17 forwardl'ijf. rlhis draws the brake beam 13 in a forward direction, forcing the shoes 16 against the periphery of the front wheels 5. is the wheels 5Y are rotated in a forward direction, an upward strain will be directed against the shoes 1G,

causing the latter to tighten upon the wheels and preventing the same from carrying mud or the like upon their periphery, said shoes scraping the mud from the wheels. The brake beam 13 being in the same plane as the bar 10 will press upon the under side of the reach pole 6 and will be thus held against upward displacement. By arranging the brake beam 13 and bar 10 in the manner shown, the tongue 9 .is much more firmly held in horizontal position. The brake beam 13 will press upwardly upon the reach pole 6 and cause the forward end of the same to rise until the movement limiting block 7 strikes the bottom of the form of brake may be employed upon wagons, of the type now in use, without alor broken they may be readily replaced at a remainder small cost without removing the of the mechanism.

lvl/'hat l claim is; y

ln a wagon brake the combination with the ruiming gear, of a brake beam positioned rearwardly of the front hounds and adapted to bear against the under side of the reach pole, shoes carried by said beam adapted for engagement with the periphery of the front wheels above the axis thereof, whereby an upward strain would be exerted against said beam and reach pole, means for operating said brake beam, and a block secured to the upper side of said reach pole and adapted for engagement with the wagon body, to limit the upward movement of said pole caused by the strain on said beam.

ln testimony whereof l have signed my Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Eatents,

Washington, D. C.
